According to Tanda, their acne spot treatment device called Zap is the "first and only device that puts the power of three proven technologies at your fingertips, it combines the same powerful blue light technology used by dermatologists with sonic vibration and gentle warming to give you clinically proven clearing results".

I'm not sure about it being the first since I wrote about a similar product before but I'm curious about this product. I rarely breakout except during really stressful days so it would be handy to have something like this to zap those zits away.

Another gadget that I want to get is the Pearl, which is a teeth whitening device.

What's good about Tanda is their "money back, risk-free" guarantee. If you're not satisfied with their product, you have 30 days to return it and they'll give you a full refund. I'll probably one of these gadgets (or both!) when I go back to the US.

There's also a nice infographic in Tanda's blog on the history of skin care.
